Selenium Grid Extras 2.0.4:org.openqa.selenium.WebDriverException:转发新会话时出错

时间:2018-04-24 11:06:04

标签: google-chrome selenium selenium-webdriver selenium-chromedriver selenium-grid

我尝试使用页面中的Selenium Grid Extras:https://github.com/groupon/Selenium-Grid-Extras

我设法在我的私人计算机上成功使用它。我运行了命令" java -jar Selenium-Grid-Extras-Jar.jar"在配置(https://ibb.co/j4wZPH)后,我能够通过转到地址http://localhost:4444/grid/console来查看节点:

然后我通过IntellIj运行测试,所有内容都按预期传递:enter image description here

但是当我尝试在公司笔记本电脑上执行相同的过程时,我收到错误消息: enter image description here

我将附上此错误的完整日志:

当我去:http://localhost:4444/grid/console时 - 我看到了这一点:enter image description here

我试图弄清楚为什么我会收到此错误并找到答案(https://stackoverflow.com/a/42187314/7967616)Selenium Grid没有任何节点可用于具有所需功能的浏览器。

但在配置过程中,我为Selenium网格节点设置了PORT 5555,它可以在我的私人笔记本电脑上运行。我在互联网上找不到答案,所以我的预感是该PORT存在一些问题,但我不知道如何检查这个问题。

任何人都有类似的问题或问题,或者可以帮我解决这个问题? 将不胜感激任何帮助。

EDITED

ChromeDriver版本为2.38(最新)

Chrome浏览器版本为66.0.3359.117(实际)

我确保自己拥有ChromeDriver和浏览器的最新版本。

3 个答案:

答案 0 :(得分:1)

解锁防火墙中的selenium extras,hub和node ports,然后它就能正常工作

答案 1 :(得分:0)

此错误消息......

Caused by: org.openqa.selenium.WebDriverException: Error forwarding the new session Empty pool of VM for setup Capabilities {browserName: chrome, version: }

...表示 ChromeDriver 无法启动与WebClient的有效连接,即 Chrome 浏览器。

如果没有 ChromeDriver ChromeBrowser 版本控制信息,您使用的二进制文件之间似乎存在版本兼容性问题,如下所示:

  • 我们不知道您的 chromedriver 版本。
  • 我们不知道您的 chrome 版本。

解决方案

  • ChromeDriver 升级到当前ChromeDriver v2.38级别。
  • Chrome 版本保留在 Chrome v66.x 级别。 (as per ChromeDriver v2.38 release notes
  • 通过 IDE 清理您的项目工作区仅使用所需的依赖项重建项目
  • 使用CCleaner工具清除执行测试套件之前和之后的所有操作系统杂务。
  • 如果您的基本 Web客户端版本太旧,请通过Revo Uninstaller将其卸载并安装最新的GA和已发布的 Web客户端版本。
  • 进行系统重启
  • 执行@Test

答案 2 :(得分:0)

我的队友帮我解决了这个问题。我不得不在Windows Defender防火墙中解锁端口。

  • 转到Windows Defender防火墙(以管理员身份打开)
  • 转到&#34;传入规则&#34;
  • 在&#34;动作&#34;添加新规则 - &gt;选择端口 - &gt;选择:
    1. 一次 - TCP
    2. 其次 - UDP
  • 提供端口(4444,3000,5555)
  • 启用连接

重复这个过程但是:

  • 转到&#34;离开规则&#34;
  • 在&#34;动作&#34;添加新规则 - &gt;选择端口 - &gt;选择:
    1. 一次 - TCP
    2. 其次 - UDP
  • 提供端口(4444,3000,5555)
  • 启用连接

重新启动系统并再次设置Selenium Grid Extras。它奏效了!
